Application filed September 18, 1912. Serial No. 720,707.

To aZZ whom it may concern:

lie it known that I, l'VALT-nn AN SON HILL, a citizen of the UnitedStates of America, and a resident of Enderlin, in the county of Ransomand State of North Dakota, have invented certain new and useful Improvements in Independent Release Attachments for Self-Binder Trips, whereofthe following is a complete specification.

This invention relates to an independent trip release for the bindermechanism of a self-binding harvester, operative independently of theautomatic trip of the binding operation and at the will of the driverwithout dismounting from the seat and without stoppage of the machine.

In. self-bindingharvesters in common use, the delivery mechanism oftenbecomes choked by damp or irregular grain, requiring the driver to halthis team, dismount from the seat and release the binder trip by hand.

The object of this invention is to provide a simple and effective deviceof this character which can be applied to harvesters already in use,which may be operated by the hand or foot of the driver, which will notinterfere with the working parts of the self binding harvesters inoperation, and which is automatically extensible and con tractible inunison with the binder head.

Figure 1 of the accompanying drawings represents a perspective view ofparts of a grain binder provided with a trip release attachmentembodying one form of this invention. Fig. 2 represents a plan partly insection of the sliding pivotal connection between a crank of the releasemechanism and the outer ends of the connecting rods of the hand and footlevers. Fig. 3 represents on a larger scale a side elevation of a partof this trip release mechanism. Fig. a represents a side elevation ofthe hand and foot release levers and the immediate connections of thefoot lever. Fig. 5 represents on a smaller scale a perspective view ofparts of an automatic tripping mechanism with which this independenttrip release is connected.

Corresponding reference characters indicate the same parts in thedifferent figures,

numbers being used for parts constituting this improved attachment andletters for old parts of the automatic trip mechanism to which thisattachment is applied.

A crank arm 10 is fixed to the cranked trip rod A of an ordinary orknown. automatic trip mechanism by a clamp 11 or any suitable means andprovided at its outer end with a crank pin 12. An extensible andcontractible or telescopic crank shaft 30 is disposed longitudinally ofthe binder frame at the outer side thereof. This crank shaft is composedof two freely intersliding members 31 and 32, which permit the automaticlengthening and shortening thereof. The parts of the members where theymterlap are square or angular in cross section or otherwise constructedso as to prevent the turning of one member on the other. The member 31is provided at its outer end with a crank 33 and the member 32 isprovided at its outer end'with a crank 34: having a duplex crank pin 35which projects at opposite sides of the crank arm. This crank may bescrewthreaded at its opposite ends and provided with nuts or othercotter fastenings 36 and 37. The far member 31 is supported at its outerend in a bracket 38 secured to the movable part B of the binder frame atone side thereof and the near member is supported at its outer end in abracket 39 secured to the fixed part C of said frame at the rear endthereof, the inner ends of these members having a sliding support oneach other. Any suitable sliding support may be employed. In the formshown the member 32 has an offset portion 32 connected at its inner endwith the body by a shoulder 32 and provided at its outer end with alateral lug 3n opposite said shoulder 32". The shoulder 32 and lug 32are provided with angular bearings disposed in alinement. The body ofthe member 31 is angular in cross section and slides freely in saidbearings, its inner end overlapping the body of the member 32. Aconnecting rod 20 connects the crank 10 with the crank 33. Thisconnecting rod is provided with a slot 21 at its outer end which isloosely engaged by the crank pin of the crank 10. A hand lever 50 ispivoted at its lower end to a bracket 51 attached to the underside ofthe binder deck and is movable in a loop 52 attached to said binderdeck. A connecting rod 40 is pivoted at its inner end to said lever andprovided at its outer end with a slot 4-1 which is loosely engaged byone end of the duplex crank pin 35 of the crank 34.

An elbow bracket comprising a vertical arm 60, a horizontal lateral arm60 and a horizontal rearward extension (30 is secured to the main frameand a horizontal bell crank lever is pivoted thereon.- A connecting rodi5 is pivoted at its inner end to one arm of said bell crank lever andprovided at its outer end with a slot 46 which is loosely engaged by theother end of the duplex crank pin 35 of the crank 34. The same arm ofthe horizontal bell crank lever 65 is provided with a lateral stud 66which slides at its outer end in a guide hole 61 in the rearwardextension 60 of the bracket 60 and an expansive spring 67 on said studtends to hold in outward position the arm of the bell crank lever 65 towhich said connecting rod is secured. The bracket 60 is also providedwith a stop 63 which is engaged by the other arm of the bell crank 65and arrests said lever at the end of its backward movement. A bracket 80is also disposed on the main frame in front of the bracket 60 and avertically disposed bell crank foot lever 85 is journaled in saidbracket. A link connects the upward arm 86 of the foot lever 85 with theouter arm of the horizontal bell crank lever 65.

In the operation of this attachment, whenever for any reason the driverfinds it necessary to release the binding mechanism before the time ofreleasing under the usual automatic action of the trip mechanism, hedepresses the foot lever 85 or pulls the hand lever 50 as may be mostconvenient at the moment. In either case the telescopic crank shaft 30is oscillated a sufficient distance to turn the trip rod A and cause thecrank D at its outer end to lift the usual stop arm E and release thedog F of the shipping pinion of the delivery mechanism. The slot of theconnecting rod 20 permits the free play of the trip rod A under theaction of the ordinary automatic trip mechanism, whereof the ordinarycrank arm Gr on said trip rod constitutes a part. The slots in theconnecting rods 40 and 45 for the hand and foot levers respectivelypermit the telescopic crank shaft 30 to turn without interference of theother when either of said levers is actuated.

I claim as my invention:
